SEALED METALLIC RECEFTACLE.

Application filed .Tune 20,

To all whom it may concern Be it known that we, HENRY E. HASTINGS, WALTER L. FARLEY, and ALBERT F. SULZER, citizens of the United States of America, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Sealed Metallic Receptacles, of which the following is a full, clear, and exact specification.

This invention relates to a metallic receptacle particularly adapted to contain a spool of sensitive photographic film, and to protect the film from adverse atmospheric conditions, such as are encountered when packages of film are stored in damp locations or shipped to tro ical countries. The container is hermetically sealed and special provision is made whereby it may be easily and quickly opened.

Reference is made to the accompanying drawin wherein the same reference characters re er to the same parts throughout.

Figure 1 is a front elevation of the receptacle as used;

Fig. 2 is a section thereof showing a spool of film (not in section) therein;

Fig. 3 is a section on line 3-3 of Fig. 1, the spool being omitted;

Fig. 4 is an enlarged fragmentary section;

Fig. 5 is a perspective view of the package showing how it is opened and the film. spool removed.

1 is a cylindrical container having a disk like end 2 and a cylindrical wall integral therewith. The container is preferably made of lead and the wall is drawn up from a sheet of metal so that it is thin and pliable compared with the end 2. In the wall 3 are two parallel weakened lines 4 and 5 extending lengthwise from the end 2 nearly to the open end of the cylinder where they join at 6, 6 the ends of a weakened line 7 that extends circumferentially around the container, except for the space between the points 6, 6. There is defined by the lines 4 and 5 a strip 8 lengthwise of the container and connected to the end portion 9 beyond the line 7.

The receptacles are made in different sizes to fit the dimensions of the various spools of film that are manufactured. The line 7 is Specification of Letters Patent.

so located that when the appropriate film spool 10 is placed in the container the flange 11 thereof will be just below the line.

The container is closed by a disk or plate 12. The disk has a central fiat portion 13 with a raised shoulder 14 around it terminating in a flange 15 perpendicular to the plane of the flat portion 13. The disk is preferably made of lead. It is placed against the end of the spool and the edges of the container are crim ed upon the flanges 15, hermetically seallng the receptacle. There is left between the shoulder 14 and the flange 11 a space 16 opposite the weakened line 7.

The package is opened by running the thumb nail or some other cutting edge around the weakened line 7, thus severing the sealed end 17 of the container from the wall 3, exceptfor the space between the corners 6, 6. This end 17 constitutes a handle by which a pull may be exerted on the strip 8 to tear it from the rest of the wall portion 3 along the weakened lines 4, 5, thus opening the container longitudinally. The flange 11 and shoulder 14 form firm abutments, so that the pliable foil is pressed across the space 16 and severed much more readily than if such a space with such side supports were not provided. One obvious advantage of this package is that while there are no obtruding tabs or handles intended to facilitate the opening, there is still a readily available rip strip by which the entire side of the receptacle may be opened up. In other words, the exterior of the package is smooth, by which we mean that it has no protuberances that may be accidentally caught, and that may thus cause the unintended opening or tearing of the cover material.

The material may be other than lead and the shape of the container may be such as to fit any contained article, the term cylindrical, as used, not being limited to an article of circular cross section. We do not limit ourselves to the particular structure described which is the preferred embodiment of our invention but we contemplate the substitution of any such equivalents as fall within the scope of our invention, as defined in the claims.

Having t us des ri ed our invention, what we claim and desire to secure by Letters Patent of the United States, is:

1. A closed metallic container with a smooth exterior between one end and the body portion of which is a continuous weakened line along which the end portion may be readily separated from the body portion, there being a strip attached to the end portion and extending lengthwise of the container, so that when the end portion is separated from the body portion, except for this strip, it may be used as a handle to pull the strip from the body portion and thus open the container longitudinally.

2. A closed and hermetically sealed cylindrical metallic container having a continuous weakened line extending lengthwise from one end of the container nearly to the other end, thence extending nearly around the circumference of the second end of the container, and thence lengthwise of the container to the first mentioned end, the weakened line thus defining one end portion integral with a longitudinal tearing strip, so that when the circumferential line has been broken the end portion constitutes a handle by ghich the tearing strip may be manipulate 3. A metallic container with closed ends and body portion, and having a weakened line extending nearly around one end, wherebythat end may be readily severed from the body portion except for a small interval, the container having two parallel weakened lines extending lengthwise thereof and joining the ends of the first mentioned line, whereby when the end is nearly severed it constitutes a handle by which the strip between the lengthwise lines may be readily severed.

4. In combination, a spool and a metallic container therefor with a disk closure, the

wall ofv the container having a weakened line therein, the edge of the disk forming an abutment against the wall of the container on one side of the weakened line and the end of the spool forming an abutment against the wall of the container on the other side of the weakened line.

5. In combination, a spool with a rigid flange and a metallic container therefor, the container being closed at one end by a disk lying closely against the flanged end of the spool and having a marginal shoulder struck from the plane of the disk so that there is an annular space between the. edge of the disk and the shoulder, the wall of the container closely fitting around the flange and disk, and having a weakened line opposite the space between the shoulder and disk.

6. In combination, a spool and a metallic container therefor with a disk like closure, the wall of the container having a weakened line extending nearly around one end, the edge of the disk forming an abutment against the wall of the container on one side of the weakened line, and the end of the spool formin an abutment against the wall of the container on the other side of the weakened line, there being a strip attached to the end portion of the container and extending lengthwise of the container, so that the end portion may be readily severed from the body portion except for the strip and when thus nearly severed it constitutes a handle by which the strip may be pulled to open the container lon itudinally.
